I think that for games, where the UI isn't probably going to be native, there is no (major) reason not to develop cross-platform. Engines like Unity or libgdx let you do just that. Other than testing, I don't see how iOS compatibility would require significant effort over an existing working Android game which was written with a cross-platform engine.
